本發明為改善農用塑膠材質及其衍生代用品所產生的大量廢棄物問題,擬選用生物可分解性高分子來取代。丁二酸丁二酯、己二酸丁二酯共聚物(PBSA)是屬於生物可分解性高分子且具有白色半結晶結構,具有強且柔軟的特性,其特性類似於線性低密度聚乙烯。由於加工性能良好可用於一般傳統的加工機械上,是目前生分解塑料加工性能最好的,但PBSA 的高結晶度使其降解速度不易調控,故本發明補強生物可降解高分子複合材料係針對以天然材料,將纖維素奈米結晶(Cellulose Nanocrystals)添加進入PBSA製備成全生物可降解複合材料,並探討以此方式所製備之可生物分解PBSA分子材料的結晶行為、材料物性、降解性等特性,以了解補強材與PBSA高分子材料形成複合材料時,於材料物性上是否能有效的提升,以及能否藉由此補強材的加入達到調控PBSA複合材料降解速率的效果。 Among the biodegradable and biocompatible polymers, poly(butylene succinate-co-adipate) (PBSA) hasrelatively excellent physical and mechanical properties. However, compared with manypetroleum-based plastics, several properties of PBS including lower degradation rate are limited forthe various end-use applications. In the study, novel biodegradable PBSA-based composites will beprepared by using the melt blending technique. Two types of natural resources, such as flax fiber andcellulose nanocrystals, will be used to reinforce the properties of composites. In-vitro degradation of PBSA-basedcomposites is also studied. Besides, thecrystalline structure and melting behavior of these composites will compare with those of neat PBSA. These could explain the relationship between degradation rate and crystallization behavior forPBSA-based composites.
